What’s Feinguss casting?

Feinguss casting or investment casting is also known as lost-wax casting. It’s a process used by investment casting manufacturers in which a duplicate metal model is made from an original model. The intricate designs and work of an original model can be remade through the investment casting process.

The feinguss casting process involves following necessary steps-

  • First of all, a wax model is prepared that is the exact replica of the metal part that needs to be made by the feinguss casting method.

  • Then follows the process of mould preparation which is the exact negative of the original wax model.

  • Wax pouring is done in the mould to form its inner lining. This hollow wax copy is then removed from the cast.

  • The removed hollow wax copy is chased by a hot metal tool to even out any marks left and the wax is dressed to hide its imperfections and give it a finished look.

  • Wax copy is then sprued with a tree-like structure that creates a path for the air to escape and for the flow of molten material.

  • This sprued wax copy is dipped in the slurry of silica and sand-like stucco and then it’s allowed to dry. After repeating this process multiple times the desired thickness of shell coating is attained. In this process the inside of the shell coating is kept hollow and it’s layered with fireproof material.

  • Shell is hardened on a kiln and the wax inside the shell is melted and runs out. After this, the shell is cooled and tested with water for any cracks. If any cracks are present in the shell then they are filled with a thick paste.

  • Traces of moisture are removed and the molted metal is poured in the shell.

  • Shell is blasted away and the rough cast is obtained. To give it the finished look the spurs are cut off and its surface is chased, smoothened, and polished.
